Method ReadVarint32

go/fory/buffer.go:1279–1286

ReadVarint32 reads a signed int32 using zigzag decoding (compatible with Java's readVarint32).

(err *Error)

// ReadVarint32 reads a signed int32 using zigzag decoding (compatible with Java's readVarint32).
func (b *ByteBuffer) ReadVarint32(err *Error) int32 {
	u := b.ReadVarUint32(err)
	v := int32(u >> 1)
	if u&1 != 0 {
		v = ^v
	}
	return v
}

// UnsafeReadVarint32 reads a varint32 without bounds checking.
// Caller must ensure remaining() >= 5 before calling.
